Results The patients were predominently female teenagers with a history of gradual onset of bilateral hearing loss, pure tone audiometry revealed symmetric ascending audiograms with moderate hearing loss at frequencies below 1 kHz, but relatively normal hearing at 2 kHz and above. Speech reception thresholds were between 40 to 85 dB HL, discrimination score was from 29% to 68%. Stapedial reflex, auditory brainstem response and compound action potentials were absent or threshold elevated disproportionately to the pure tone threshold. All of the patients had normal cochlear microphonics and robust spontaneously and transiently evoked otoacoustic emissions, the TEOAE showed no contralateral suppression effects as seen in normal subjects.

结果 该病多在青春期后起病，女性较多发，表现为渐进性双耳对称性听力下降，纯音听力以低频损失为主，语言接受阈升高，分辨率下降，镫骨肌反射及ABR引不出或阈值明显升高与纯音听力不成比例，耳蜗微音器电位正常，听神经动作电位引不出，耳声发射波幅高、时程长且不为对侧声刺激所抑制。

The minimum fluidization velocity has a minimum value when the frequency of sound waves is 120Hz and it will decrease as the sound pressure level increases. The degree of sound attenuation will increase while bed material is higher and the fluidization quality of fine particles will become poor and the minimum fluidization velocity will increase. Compared with TiO2, the SiO2 fine particles have a better quality of fluidization at the same fluidized conditions.The cluster/subcluster model and oscillators model are used to describe the fluidization characteristics of fine particles in a sound-assisted fluidized bed. The theoretical calculations show that the minimum fluidization velocity umf is decreased with the SPL increased at the same frequency of sound and the quality of fluidization is better.

论文还系统的考察了声压和频率对纳米SiO2和TiO2颗粒流化特性的影响，结果表明：在频率一定的情况下，声压越高，流化床中形成的聚团尺寸越小，最小流化速度越低，流化质量越好；当声压低于120dB时，声场对超细颗粒流化特性的影响减小，当声压大于130dB时，则能显著改善流化效果，使流化床内的颗粒聚团明显减小，最小流化速度明显降低，粉体带出减小；声压一定，频率为120Hz左右时，最小流化速度最低，此时流化床中形成的聚团尺寸最小，流化效果最好；超细颗粒达到较好的流化状态存在一个最佳频率范围，随着声压增高，这个频率范围将增大。

From acoustic wave equation, current continuity equation and boundary conditions, we have solved the interface potential produced by BAWs in interface between piezoelectric solid and semiconductor. The results of YZ LiNb03/n-Si structure with SV wave incidence have been calculated and experimental result has been given. Finally, we have presented some kinds of BAW acoustoelectric convolver structures and analyzed their features.

Sheng-Yuan Huang's works in Yi-Lan show quite different appearances from the general public buildings in recent years in Taiwan. In terms of the locality in his works, Huang is treated as one of the representative regionalistic architects in Taiwan. In the context while the widespread globalization has cast influences on local architecture, Huang put his works into practice to question the vague development in built environment. Through the case study of Huang's public works in Yi-Lan, we may offer a framework of reference in seeking the position in the development of current Taiwan architecture.

近年来，黄声远建筑师在宜兰地区的建筑作品表现出不同以往台湾公共建筑的空间操作形式，透过其作品所反映出的地方色彩，使得黄声远被视为台湾本土地域性建筑师的代表之一，现今地方建筑普遍受到全球化影响的同时，黄声远的建筑作品从本土文化脉络发展出地域性空间的实践，提出对全球化发展的反思。

Integrating the sound intensity vector on the area which surrounds a sound source gets the sound power of this sound source. Since the integral of the sound power of the sound sources which are not enclosed by the area is zero, one could measure the sound power in ordinary environments correctly by measuring sound intensity.

对于一个声源，只要将其包络面上的声强矢量作积分，就可以求出被围声源的声功率，而测量区域之外的干扰噪声得以抵消，因此可以在普通环境下能准确地测定声源声功率。

I can call back the solemn twilight and mystery of the deep woods, the earthy smells, the faint odors of the wild flowers, the sheen of rain-washed foliage ⑴, the rattling ⑵ clatter of drops when the wind shook the trees, the far-off hammering of woodpeckers ⑶ and the muffled drumming of wood pheasants ⑷ in the remoteness of the forest, the snapshot ⑸ glimpses of disturbed wild creatures scurrying through the grass—I can call it all back and make it as real as it ever was, and as blessed.

我仍然记得神秘的树林深处的缕缕光线令人肃然，空气里弥漫着泥土芬芳的气息，野花散发出若有若无的清香，雨后的植物闪烁着晶莹的光彩，还能听到远出隐隐传来樵夫的锤子声，森林深处的野鸡的喃喃声，偶尔还能瞥到受惊吓而匆忙穿过草丛的动物。对于这些就像希望的那样，仍然历历在目。

Then somebody laughed, then the entire class was laughing, and not in contempt and ridicule, but with open-hearted enjoyment.

有人笑出声来，接着全班都笑了，不是轻蔑嘲弄，而是乐乎乎地开怀大笑。

In this respect, what is original is to determine what parallel motion is heterophony texture, to dig up a new heterophony texture-- development heterophony, to make a choice of using both comprehensive heterophony and composite heterophony, and to make a definite differentiation between the both.

在这一内容上，具有创新意义的是确立了哪种平行进行属于支声织体，挖掘出了新的支声织体展开性支声，做出了综合性支声和混合性支声并用的选择，并对其进行了明确的区分。

Just where she had paused, the brook chanced to form a pool, so smooth and quiet that it reflected a perfect image of her little figure, with all the brilliant picturesqueness of her beauty, in its adornment of flowers and wreathed foliage, but more refined and spiritualised than the reality.

别怕！她开头也许会认生、害躁，但很快就会爱起你来的！这时，珠儿已经来到小溪对岸，站在那儿不出声地瞅著海丝特和牧师，他俩依旧并肩坐在长满青苔的树干上，等著见她。就在她停下脚步的地方，小溪恰好聚成一个池塘，水面平

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
